Problems solved by technology

[0009] A challenge in the prior art is the configuration of a hulled amphibian with fins that allow coordinated turns while operating in water without significantly affecting the aerodynamic performance of the aircraft in the air
Another challenge is that an amphibian equipped with fins can turn at moderate speeds without submerging the fins

Embodiment Construction

[0023] According to the accompanying drawings, the embodiments of the present invention will be described in detail below. Although the present invention has been described and illustrated with a certain degree of particularity, those skilled in the art will understand that the present disclosure is only carried out by way of example, and Numerous changes may be made by combining and installing parts without departing from the spirit and scope of the invention.

[0024] A lateral stabilization system including a buoyancy system and a wingtip system associated with an amphibian is described hereinafter by way of example. It is well known in the art that seaplanes, or aircraft whose fuselage is used as a waterborne vessel, have little lateral stability in water. To enhance the lateral stability of this seaplane, the stabilizers or buoys are displaced laterally from the centerline of the fuselage. This stabilizer provides sufficient lateral stability when the aircraft is parked....

Abstract

A system for enhanced lateral stability of an amphibious aircraft includes a buoyancy system laterally displaced from opposite sides of the fuselage of the aircraft and wingtip system having a hydrodynamic planing surface associated with each wingtip. The hydrodynamic planing surface on each wingtip prevents the submersion of an associated buoyancy structure. By supplementing the lateral stability of the buoyancy structures using hydrodynamic planing surfaces, the combined lateral width of the fuselage and buoyancy structures can be reduced without detrimentally impacting operational performance. This reduced lateral width enables the amphibious aircraft to be configured for storage and transportation on a trailer or shipping container.

Description

[0001] related application [0002] This application claims priority to US Patent Application Serial No. 12 / 482,336, filed June 10, 2009, which is hereby incorporated by reference in its entirety. technical field [0003] Embodiments of the present invention relate generally to amphibians, and more particularly to the interaction between stabilizers and wingtips of amphibians. Background technique [0004] An amphibian is an aircraft that can operate on both land and water. When on land, landing gear or similar structures extending from the fuselage of the aircraft allow the aircraft to operate as a conventional landplane. When operating in water, amphibious aircraft generally fall into two categories: 1) float-planes and 2) hull-type planes. In a pontoon seaplane, a conventional aircraft is mounted on two outer buoys, also called pontoons. When operating in water, only the buoy box or outer buoy stays in the water. In a hull-type aircraft, the actual aircraft fuselage i...
